Some bugs are caused by bad assumptions.
These assumptions can cause widespread problems.
Find the first error.
A large series of errors is usually triggered by a single error.
Write a test for every fault you find.
It’s a simple way to avoid repeating mistakes.
Don’t count on others to test.
Do your job and be responsible.
Testing can find bugs, but it can’t prove the absence of bugs.
It can certainly find bugs, but it is not proof that all is well.
Never ignore an error.
You can’t simply pretend it didn’t happen.
Comments should discuss the current functionality.
Don’t let your comments ramble on about the past or future.
Don’t use comments as version control.
Instead, use version control software, like git.
Avoid comments at the end of a code block.
Your block is probably too big.
